Use the associative property to get:

(-16.75 + 16.75) + 5.72

On Friday, Elsbeth deposited her pay check for $872.56. What was the account’s final total?
-$866.84
$878.28
$895.03

Answer 1

balance on tuesday : - 11.03

balance on thursday : 5.72

872.56 + 5.72 = 878.28

balance on friday : 878.28

Explanation:

Answer 2

New balance = $ 5.72

Account final balance = $ 878.28

Explanation:

The new bank balance = -$ 16.75 + $ 5.72 + $ 16.75

= $ 5.72

The cumulative property:

-16.75 + (22.47)

= 5.72

associative property:

(-16.75 + 16.75) + 5.72

= (0) + 5.72

= 5.72

The account final balance = $ 5.72 + $ 872.56

= $ 878.28
